The accuracies of a VU meter and a peak-program (PPG) meter (EBU meter) for measuring program levels are examined by means of dual strip-chart recordings of various types of program material. It is shown that the VU-meter measurements are highly dependent on the program material, while the PPG meter does not suffer this shortcoming. The use of a PPG meter results in a program volume that is 4-5 dB greater than when using a VU meter. The stripchart recordings also show that the PPG meter makes…

We deal here with two related problems faced by the user of television modulators: the problemn of initially setting modulation and the problem of maintaining it over a long period of time. Actually,
Realization of Microphone Volume Intensity Indication
In many desktop applications, an audio signal is captured from the microphone. Unfortunately, most applications lack quality visual indication of arousal microphone volume, which would clearly
